The rate of flow in the tank cannot be assistedby pressure, but it can be assisted by velocity if the stream is di-rected into the tank properly. For instance, if the inlet is in theend of the lank and the water is directed lengthwise of the tank,then the water may be forced into the tank at considerable velocity,and so reduce the time of flow to the opposite end of the tank ; onthe other hand, if the water is admitted vertically through the pot-.

Drainage must be provided for the crane pit. Forproper security a gate valve should be placed inside of the cranevalve, and there should be another valve near the reservoir tank. Track Tanks.—Track tanks are made 0 ins. or 7 ins. deep and ISins. to 20 ins. wide; they are placed central between the rails ofa track, and the top of the tank, or, more particularly, the level ofthe water in the trough, must bear a fixed relation to the top of therail. The tanks are of various lengths; some are 1,200 ft. long,others 1,400 ft. long, and others are 1,000 ft. long, and the LakeShore & Michigan Southern is making them 2,500 ft. long wherethere is room. The length is determined by the maximum amountof water which is to be delivere
